In recent years, with the continuous development and utilization of oil and natural gas, the reserves, development and service life of oil and natural gas energy at home and abroad have to be worrying. All countries are working hard to save energy, reduce emissions and develop new energy sources. Among them, shale gas as a new energy, its exploration, development and utilization has been put on the agenda.
Shale gas is mainly located in dark shale or high carbon shale. Shale gas is natural gas in adsorbed or free state on the main body of shale rock, high carbon mudstone, shale and silty rock interlayers. It can be generated in various stages of organic origin and exist in cracks, pores and other reservoir Spaces in free phase state (about 50%).
Shale gas development has the advantages of long mining life and long production cycle - most of the gas-producing shale is widely distributed, thick and generally contains gas, which makes the shale gas well can produce gas stably for a long time. However, the shale gas reservoir has low permeability and is difficult to exploit. As the world's energy consumption continues to rise, including shale gas, more and more attention is paid to regular energy. Countries such as the United States and Canada have achieved commercial development of shale gas.
However, the development model of shale gas is basically similar to the development of oil, natural gas and coal bed methane in principle. It is also a process of exploration, drilling, collection and utilization. It is also through the drilling rig in the mud solid control system of vibrating screen, vacuum degasifier, desander, desilter, drilling fluid centrifuge and other main solid control equipment of the five-stage purification and mud tank, sand pump, mud agitator and other auxiliary solid control equipment as well as the role of other auxiliary equipment of the drilling rig to complete shale gas drilling.
Xi 'an KOSUN has been engaged in the research and development and production of mud solid control systems in the fields of oil and gas drilling, trenchless engineering, coalbed methane development, shield tunneling and river dredging for many years, and has accumulated certain experience in supporting solid control in the field of shale gas development drilling.
